Pombi yakarairwa pasi pechirevo ichi ndeyekushandira kumanikidzwa patembiricha yepamusoro ye350℃.
Pombi isina chinhu, chifukidziro chitema kana chidzikiso chinopisa chakafukidzwa ne zinc (chakagadziriswa);
Muzvisungo zvine zvisungo zviviri zvedonje;
Migumo yese ine zvidziviriro zvekupedzisira;
Mugumo usina kuzara, mugumo we bevel (Kana mutengi achida uye S≤22mm, mugumo wepombi unofanira kuvharwa, dhigirii: 30° (+5°~0°), uye ukobvu hwemadziro emudzi hauderedzwe ne <2.4mm.);
Kumaka.

Basa rekuisa mapaipi esimbi reJIS G3454 ERW chinhu chakakosha pakugadzirwa nekugadzirwa kwemapombi esimbi eERW. JIS G3454 inyanzvi yeindasitiri yeJapan inotsanangura mapaipi esimbi ecarbon kuti ashandiswe pakumanikidzwa kwakanyanya. Pombi yesimbi yeERW (electrical resistance welded) inogadzirwa nenzira iyo mipendero yemachira esimbi kana zvidimbu zvinopiswa uye zvinosanganiswa pamwe chete pasi pekumanikidzwa, zvichigadzira pombi isina musono uye yakasimba. Mabasa ekuisa mapaipi anobatanidzwa mukugadzirwa kwemapaipi esimbi eJIS G3454 ERW anoita basa rakakosha mukuona kuti mapaipi aya akanaka uye akavimbika. Mabasa ekuisa mapaipi anosanganisira kushandiswa kwemichina ine simba guru kugadzira mapaipi zvichienderana nehukuru hwaunoda uye zvirevo. Maitiro aya anoita kuti pombi ive nemagumo akatsetseka uye akarurama, uye ukobvu hwemadziro hwakafanana muhurefu hwayo hwese. Chimwe chezvakanakira zvikuru zveJIS G3454 ERW steel pipe press services kugona kugadzira mapaipi ane divi rakarurama uye kuvimbika kweweld. Mabasa ekuisa mapaipi anobvumira kutonga kwakasimba pamusoro pemaitiro ekugadzira, kuve nechokwadi chekuti pombi inosangana nezvinodiwa uye zvirevo. Pamusoro pezvo, kushandiswa kwemichina ine simba guru panguva yekugadzika mapaipi kunobatsira kugadzira mapaipi ane simba rakasiyana uye kugara kwenguva refu, zvichiita kuti akwanise kushandiswa mumabasa akasiyana-siyana muindasitiri dzakadai semafuta negesi, kuvaka, uye mota. Pamusoro pezvo, masevhisi ekugadzika mapaipi esimbi eJIS G3454 ERW anogonawo kugadzira mapaipi akatsetseka uye akanaka. Michina inoshandiswa mugadzika mapaipi inogona kupukuta nekunatsa pamusoro pepombi, zvichikonzera chigadzirwa chinotaridzika zvakanaka. Izvi zvakakosha zvikuru kune mashandisirwo apo mapaipi anoonekwa kana kuoneka sezvo anowedzera chitarisiko chose uye anovimbisa kupera kwemhando yepamusoro. Mukupedzisa, masevhisi ekugadzika mapaipi esimbi eJIS G3454 ERW chikamu chakakosha chemaitiro ekugadzira, ichivimbisa kugadzirwa kwemapaipi emhando yepamusoro uye akavimbika ekushandiswa kwakasiyana-siyana kwekumanikidza. Inovimbisa kururama kwehukuru, kuvimbika kweweld, uye nzvimbo dzakatsetseka, zvichiita kuti mapaipi aya akwane mumaindasitiri akasiyana-siyana nekushandiswa.
